Five sense had been our to for some time, but the price has crept up to that $60 per kg mark so normally only buy them when they come on special.
The roastary is just down the road from me so can order and just go pick up, so know we are always getting freshly roasted beans. They also have a roastery over east.
The biggest issue for me with the supermarket beans is they are generally fairly old by the time you get them in your cart, and many lack roast dates.
But, it depends a lot on what taste you prefer in the cup and how you drink your coffee, I know for a lot of people older coffee isn't an issue as long as it kind of just tastes like coffee. I've been spoiled since marrying a barista.
I did find a freshly roasted batch of Brew Coffee Roasters Huila blend at a local independent grocery store and really enjoyed them. Could really get the stone fruit flavour in my espresso, wasn't bad with milk and think they would work well for filter coffee too (although I ran out before I tried that). I think the shop I got them from had them on special as it was only $16 for 500g. On the website it's $27.50 for 500g or $45 for a kilo.
But independent grocery stores are normally a good option for a selection of independent roasters and they normally have a roast date. I prefer within a week of roast date, but will go up to three weeks from roast if I'm out of coffee at home 
Generally I consider $40 per kg and below a bargain for decent coffee and up to $50 expected... above $50 and it's starting to get expensive.
I also didn't mind Dimattina. They have a roastery here in Perth and in Melbourne, but I don't live near them any more so rarely get their beans.
Also recommend keeping an eye on OzBargain. Some roasters will post some good discounts up there.
